PRIME B450M-A (Socket AM4) DDR4 MATX Motherboard
The B450 chipset forms the centrepiece of the ASUS PRIME B450M-A motherboard and has been specially developed and optimised for 2000- series (Pinnacle Ridge) Ryzen CPUs. B450 motherboards support all features of 2nd gen Ryzen processors, such as the AMD's new XFR2 overclocking. Additionally, the motherboards support up to 64 GB of RAM with a guaranteed clock frequency of 2.933 Megahertz. Overclocking to higher frequencies is also an option, although the increase will depend on the motherboard.
The Features of the ASUS PRIME B450M-A at a Glance:
- 1x PCIe 3.0 x16 (x16) for high-end graphics card
- 2x USB 3.1 / 6x USB 3.0 / 4x USB 2.0
- 1x M.2 (PCIe 3.0 x4 & SATA6G) / 6x SATA 6G
- DDR4-RAM up to 3.200 MHz via OC
- LED lighting & RGB header
The Features of the ASUS PRIME B450M-A in Detail:
The ASUS PRIME B450M-A Micro-ATX motherboard offers a PCI-Express 3.0 slot with full x16 connectivity for graphics card. For additional expansion cards the motherboard offers two PCIe-x1 slots. The four RAM slots support up to 64 GB DDR4-RAM clocked at up to 2.933 MHz and this can be increased to up to 3.200 MHz via OC.
An M.2 slot with four PCIe Lanes and a SATA 6G interface is available due to the motherboard being AM4-compatible. M.2 SSDs use the advanced NVM-Express protocol (NVMe) and support, thanks to the PCI-Express 3.0 connectivity, speeds of up to eight times faster than those of SATA 6G hard drives. This means data transfer speeds of up to 32 Gbit/s are possible.
The ASUS PRIME B450M-A offers two USB 3.1 connections on the back. USB 3.1 Gen 2 ports are capable of achieving speeds of up to 10 Gbit/s per port and USB ports while also supporting the fast charging function used by many smartphones and tablets. For CPUs with integrated graphics like AMD's Raven Ridge APUs, the board offers HDMI-, DVI- and D-Sub connectivity.
In terms of special features offered by the ASUS PRIME B450M-A, it also offers LED lighting zones. Additionally the board provides one header for static RGB-LEDs as well as a stable power delivery system for the CPU.
